Pani, I made some more changes to the input based on peer review - use the attached version rather than the previous version.

FW: Peer Review of SE Input for Vermont Yankee Core Plate Bolt Analysis (ME6248)

Pani, attached is my input to the SE for the areas that I reviewed - specifically, the determination of the amount of preload loss and the adequacy of the proposed inspection plan. Ganesh peer reviewed for me, see email below.

I'm not sure how you structured your SE, so feel free to move things around and cut and paste my sections as needed. We probably should meet to discuss. I'll be in the office tomorrow and Thursday.

Thanks, Jeff From: Cheruvenki, Ganesh .A-Sent: Tuesday, February 14, 2012 10:20 AM To: Poehler, Jeffrey

Peer Review of SE Input for Vermont Yankee Core Plate Bolt Analysis (ME6248)

Ganesh, As discussed yesterday, please peer review (technical only) my SE input for Vermont Yankee. Use TAC ME6248. Note that it is not a complete SE because Pani has the lead on the SE. He can integrate my inputs into the structure of his SE.

If you can give me comments by the end of the week that would be fine.

Pat, I copied you so if you have time to review your comments would also be appreciated.

Thanks, Jeff 9
